Hi all,

Just out of curiosity, is anybody on here using the ipid touch 7th gen?

If so, has anybody tried with sensitive IEM's or know the output impedance?

Thanks!

No don’t use a iPod touch but seems like most of them have a 5 ohm output impedance but could only find that for a 6th gen so don’t know but seems like the other versions were the same.

Yea, I would expect of an Apple portable device's headphone jack output impedance to be under 10-Ohm, like around 5-Ohms, give or take.
If Apple was smart, under 5-Ohms.

Interesting, would you mind sharing where you found this? I've read in a couple places that the output impedance of the 6th gen was something like 1.7ohms for the ipod touch.

This wasn’t it but another that says 5.https://www.head-fi.org/threads/ipod-output-impedance.583426/

Ah I see, thank you very much!

I would guess around 1.5 ohms based on how it sounds with CA Andromeda IEM

I see in your signature that you use the Ipod touch 7th and the Andromedas, do you like this pairing? Is there any hiss?

The reason I ask is I am looking for a portable player with minimal hiss for my Campfire Orions, which have a similar impedance to the Andromedas. I'm attracted to the ipod for it's tried and true user interface. Thank you!

I like this pairing a lot. It brings all the good things about the Andromeda IMO. Zero hiss whatsoever with the Andromeda. I've never heard any IEM I've demoed with the iPod Touch 7 that hissed BTW

That is excellent news to me! I'm more concerned with the actual sound than the impedance, so this makes me confident enough to give it a shot. Thank you for your help!

Sorry but you can tell 1.5 ohm output impedance from say .73 and 1.74 or 3.91 ? Damn your good.

You got me there. I just had a few sips while replying lol. It sounds almost exactly the same as the iPod Touch 6G which has a measured 1.74 ohm OI. It's known that CA Andromeda changes its sound signature based on the DAPs OI

What about the output power?
